Blake Oliver needed to file a City of Los Angeles business tax return for his last remaining bookkeeping client. Instead of spending 30 minutes clicking through websites and copying numbers, he gave Claude Cowork a single instruction: “Search my email for info about the account and help me file it on the city website.”
What happened next, documented on a recent episode of The Accounting Podcast, shows exactly where the accounting profession stands with AI adoption. The AI agent searched Blake’s email, found the tax notice, extracted the business details from a PDF, logged into the city website, navigated to Xero to pull gross receipts, filled out the return, and drafted the client confirmation email. Total human involvement: one correction when it pulled accrual instead of cash basis numbers.
“This is a task that might take 15 to 30 minutes if you filled out a time sheet. Claude just did it,” Blake told co-host David Leary during their weekly news roundup.
The Numbers Show AI Closing In Fast
OpenAI didn’t just release another model update with ChatGPT 5.4. It specifically targeted the kind of work that fills an accountant’s day. As David read from OpenAI’s announcement, the company “put a particular focus on improving GPT 5.4’s ability to create and edit spreadsheets, presentations, and documents.”
The benchmarks back up that focus. Using something called GDPval—which measures performance on real-world knowledge tasks across 44 occupations—ChatGPT 5.4 now beats or ties industry professionals 83% of the time. On spreadsheet tasks specifically, it jumped from 68% accuracy to 87% in a single generation.
“It’s getting close to that 90% success now on everything,” David observed. For context, that means if you give an accountant and this AI the same spreadsheet task, the AI will match or beat the human’s performance nearly nine times out of ten.
Real Accountants, Real Work, Zero Software Costs
While Blake was experimenting with Claude for business tax returns, a developer went further. Fed up with TurboTax, he used Claude to complete a 42-page federal return plus two trust returns, all at zero software cost beyond his AI subscription.
His approach was surprisingly low-tech: Downloaded blank PDFs from the IRS, have Claude fill them out, then print and mail. The biggest challenge wasn’t getting the AI to do the calculations or understand the tax code. It was trying to make it work with the IRS’s online fillable forms. So he skipped that part entirely.
“The comments were like, ‘Can I quit doing my returns tomorrow? I’ve been waiting for this my whole life,'” David said, describing the reaction from tax professionals who saw the developer’s work on social media.
The timing is notable. These experiments happened during tax season, when practitioners are supposedly too busy to explore new tools. Yet here’s a developer replacing TurboTax with Claude, and Blake casually using an AI agent for client work.
The Privacy Excuse Just Disappeared
Most firms claim they can’t use AI because client data is too sensitive. This week, Zapier offered a solution to the privacy problem.
Its new AI Guardrails can detect over 30 categories of personally identifiable information, redact sensitive data before it reaches AI systems, block workflows when it detects problems, and identify attempts to manipulate the AI. You insert it as a step in any workflow, and it sanitizes the data before AI ever sees it.
“If you have client data being passed through Zapier into any AI tool, go add this step to your workflows,” David advised listeners.
Blake was even more direct about the implications. “I totally see this being a huge tool for accounting firms, because we have all this information we want to use with AI. But a lot of it is too sensitive. That’s the main reason most firms aren’t doing anything with it.”
Beyond AI: The Week’s Other Bombshells
While AI dominated the discussion, Blake and David covered several other major stories that accounting professionals need to know about, including:
The Botkeeper Collapse Gets Messier
In an interview with Accounting Today, CEO Enrico Palmerino claimed the company went from healthy to dead in eight days. But Blake uncovered how Botkeeper engineered its financials by selling their bookkeeping clients to a firm called Benchmark Cloud Accounting. It then had that firm buy a multi-million dollar Botkeeper license. “That is how you turn service revenue into SaaS recurring revenue,” Blake explained.
Iran’s Drone Economics
The cost disparity between Iran’s drones and America’s million Interceptor missiles raises questions about the financial sustainability of current military strategies. “We’re spending $3 million to shoot down something that costs $20,000 to $50,000,” Blake pointed out.
KPMG and Polymarket
Anonymous accounts on the prediction market Polymarket have been suspiciously successful at betting on earnings for companies audited by KPMG- (and only KPMG) audited companies. The amounts are small so far, but as David noted, “Are they doing it on the real derivative markets as well?”
Record 401(k) Withdrawals
Vanguard reports hardship withdrawals have tripled since 2020, jumping from under 2% to 6% of participants. Despite positive business sentiment, individual financial stress is climbing.
What This Means for Your Firm
General-purpose AI agents can complete multi-step workflows across email, accounting systems, and government websites. The privacy barriers that kept firms on the sidelines now have concrete, deployable solutions. The capability exists. The safety tools are live. The only question is timing.
Blake’s Claude experience offers a preview of the emerging division of labor. AI handles the execution, humans provide the judgment. The AI pulled the wrong basis for the numbers. Blake caught it. That’s where professional value lives now, not in the clicking and copying, but in knowing what the AI doesn’t know to check.
The message might seem poorly timed to practitioners overwhelmed by tax season. But accountants are eager for tools that eliminate the drudgery, even in the thick of deadline pressure.
Listen to the full episode to hear Blake walk through his Claude workflow step by step, get David’s take on what ChatGPT 5.4’s benchmarks really mean, and understand why the Botkeeper story matters for anyone considering AI-powered bookkeeping solutions. The episode reflects a profession at an inflection point—not in some distant future, but this week.
